Definitions

  • the present invention consists of a compound tile with a natural stone visible face, preferably marble, of the type comprising a plate of natural stone of reduced thickness and firmly fixed by adhesive means to a rigidification and strengthening supporting sheet, said support having a particular composition which is adapted to the physical characteristics of the natural stone plate.
  • the present invention also consists of a process for manufacturing the above-mentioned tiles, in which the union between the natural stone plate and the supporting plate is made by stacking and curing the adhesive between plate and sheet in an oven.
  • the compound tile with natural stone visible face of the present invention has a special application in all sectors which commonly use natural stone, mainly for decoration.
  • honeycomb panel structures require the use of especially light materials which increase the cost of the finished product, not only due to the material but also to the greater volume, which affects material transport costs.
  • the compatibility between the physical and chemical features of the minerals and the supporting materials is not analysed in relation to different physical effects which would influence the features of the final product, making its use and assembly complicated and unreliable.
  • fibre wood, cellular structures of fibreglass and asbestos and even derivatives of Portland cement may be used.
  • the applicant is able to separate them after cutting without falling and then to introduce a strengthening sheet between each sheet, preferably also made of light material and with a honeycomb panel structure, which carries with it the drawbacks mentioned above.
  • Adhesion of these supporting sheets to the natural stone sheets is carried out in this position, although it is not clear how application of the adhesive is carried out since if it is done in a vertical position an even application of said adhesive will not be obtained, which will affect the characteristics of the final product.
  • the feasibility of the manufacturing process and the strength of the compound tiles with a natural stone visible face stems mainly from the correct composition of the strengthening support material whose physical and chemical features must conform as far as possible to those of the natural stone so that they react in a similar way to the same physical or chemical reactions so that the compound tile is as stable as possible.
  • Several materials may be used as a support for the natural stone plate, and different patent applications disclose the use of fibre materials, EP0252434, Leis, or polyurethane, EP255795, Rigas.
  • an object of the present application is to obtain a supporting sheet for the natural stone plate with particular composition and materials which provide said sheet with similar characteristics to those of the natural stone plate so that their behaviour will be as similar as possible and the resulting stone product will have greater strength and said supporting sheet will have less thickness, particularly using fibre cement.
  • it is necessary to prevent the distortions which occur in the fibre cement sheets mentioned in the state of the art when they absorb and release humidity, and which cause the natural stone plate to curve, becoming functionally unacceptable as a result and even breaking.
  • To increase the stability of the resulting tile it is necessary to increase the stability of the supporting sheet, which mainly consists of reducing the movement of humidification.
  • the supporting sheets which use fibre cement described in the state of the art as a support for natural stone plates absorb humidity and release it, causing size increases. Because the fibre cement sheet is stuck to the natural stone plate, said size increases affect the tile resulting from said adhesion, making the tile curve and even break or crack.
  • Another object of the present invention is to provide improvements in the manufacturing processes used up to the present time for obtaining compound tiles with a natural stone visible face by means of introducing new materials and conditions into the industrial process.
  • the objects mentioned above are, in accordance with the present invention, achieved by using a supporting sheet made up of a light sheet of reduced thickness to configure the tile with natural stone visible face, the purpose of said sheet being to strengthen the natural stone plate.
  • the problem described above has been resolved in accordance with the invention by proposing and testing different materials and means to achieve on the one hand a reduction in the movement of humidification and on the other a reduction in resistance to the usual bending of fibre cement, pressed and cured in an autoclave, which has been chosen to make up said supporting sheet.
  • the movement of humidification is proportional, among other variables, to the cement content, to the inverse of the particle size and to the inverse of the density, variables which it has been necessary to modify by means of many test runs to achieve a greater stability of size.
  • the cement content should be decreased, the sand content should be increased and the average size of the particles of the mixture should also be increased and, at the same time, the fibre percentage should be reduced in order to increase density.
  • the products subjected to treatment in autoclave undergo an increase in their movement of humidification as they age.
  • stabilising elements have been introduced into the composition, such as kaolin, alumina and mixtures thereof, which produce doping of the mould, retarding and reducing the effect of ageing.
  • Another important factor in achieving size stability is to retard as far as possible the size changes caused by the movement of humidification, caused by the absorption of water into the fibre cement.
  • water repellents are included either in the paste or on the surface, or advantageously in both, which retard the penetration of water into the fibre cement or prevent it if it does not reach a sufficient pressure. These water repellents may be organic, inorganic or mixed.
  • the reduction of resistance to bending in the fibre cement is necessary since the movement of humidification never reduces completely and therefore the fibre cement sheet will always undergo small size changes. According to the force which the fibre cement exerts upon the natural stone, the latter will distort or not. Therefore, the distortion of the compound tile depends upon the resistance of the fibre cement: the greater the resistance the greater the distortion.
  • the effects of a reduction in the resistance of fibre cement which is pressed and cured in an autoclave mainly by reducing the percentage of cement and cellulose in accordance with the invention to values of 32-34% and 4-5% respectively, causes a significant increase in density and a reduction in bending resistance from values which are typical of fibre cement which is pressed and cured in an autoclave of 22 Mpa to values of 12 Mpa.
  • a fibre cement is known in the state of the art, with a low fibre content as described in patent application EP484283 filed by Tappa.
  • a manufacturing process for asbestos-free fibre cement is described which uses a completely different technology, air curing, giving rise to a type of fibre cement of lower quality and reliability, whose application as a supporting sheet is neither mentioned nor suggested, not being appropriate for this purpose, but only as a covering.
  • Said fibre cement is made up of cellulose fibres, Portland cement, flocculant and strengthening fibres of polyvinyl alcohol. After mixing the different components, the compound is introduced in controlled temperature conditions but without subjecting it to chemical treatment or pre-treatment, nor, in contrast to the type of fibre cement used, to the pressing and curing operations in autoclave necessary for the objects of the present invention.
  • a fibre cement sheet which fails to comply with the typical characteristics of the same for covering facades, and as such, when laid out in the form of a sheet is extremely weak and fragile, the decrease in cement and fibre being as great as possible, provided that it allows handling and cutting operations to be carried out, but when adhering to a natural stone plate it increases the strength of the latter, allowing thicknesses which are impossible to use without the sheet described above and with a minimum of distortion due to humidity or temperature.
  • the supporting sheet is made up of a light sheet of reduced thickness, comprising a mixture of cement (20-35%), silica (40-50%), sand (5-10%) and cellulose fibre (4-8%), similar to fibre cement but with mechanical and chemical features which are different from the standard ones of fibre cement, obtained by pressing and autoclave curing.
  • a mixture of cement (20-35%), silica (40-50%), sand (5-10%) and cellulose fibre (4-8%), similar to fibre cement but with mechanical and chemical features which are different from the standard ones of fibre cement, obtained by pressing and autoclave curing.
  • sand and stabilising and water-repelling agents are added to the paste or to the surface of the exposed faces of the tile.
  • the cement and fibre content is very low in comparison with the standard amounts of fibre cement which is pressed and cured in an autoclave, but high enough to allow cutting and handling operations of the light sheet so that it may be stuck to the natural stone plate as described below.
  • the reduction in cement and fibre content provides a high density in relation to other fibre cements and, as described above, a reduction in bending resistance and a reduction in the movement of humidification.
  • Another additive which may be added to the supporting sheet mixture is a pigment which is, for example, stable in light, with the possible purpose of differentiating some compound tiles from others so that they will withstand conditions out of doors.
  • the compound tile consists of a supporting sheet and a natural stone plate, which adhere together by means of an epoxy resin with two components, which incorporates a percentage of micro-granules or micro-nodules with a determinate diameter.
  • the supporting sheet of the natural stone plate is used to manufacture compound tiles in a manufacturing process made up of different stages:
  • plates are cut with a thickness of more than twice that of the final thickness of the natural stone plate of the tile to be obtained;
  • the sheets of pressed and cured fibre cement are arranged in large sheets. From said sheets the sheets are obtained which will serve as a support for the natural stone plate by means of cutting according to the size of the natural stone plate. Said fibre cement sheets are to be dry and clean since in order to stick the natural stone to the supporting sheet, the faces which are to be stuck must, at the time they are joined, be clean, dry (by means of an appropriate prior process) and at a determinate temperature so that the application of glue as well as the subsequent sticking and permanent adhesion are optimal. An epoxy adhesive with two components is used for this operation. The supporting sheets or fibre cement stick to each one of the two faces of the natural stone plate, thus forming modules of fibre cement-natural stone-fibre cement.
  • the lower supporting sheet of each one of the modules has a larger surface size than the other sheet of fibre cement and larger than the natural stone plate, and is provided with additional shapes at its periphery which serve to retain the surplus resin when said pressure is applied to the stack of modules.
  • Said additional shapes consist of peripheral channels and/or an adhering perimetric strip which prevent the surplus resin which is expelled when the modules are compressed from sliding down the stack of modules and causing the problem described above.
  • the modules After stacking the modules and exerting permanent vertical pressure upon the stack, for example by means of bracing means which relate the upper sheet of fibre cement of the module situated at the highest position in the stack with the lower sheet of fibre cement of the module situated at the lowest position of the stack, the modules are introduced into an oven for curing the adhesive between the natural stone plates and the sheets of fibre cement at a determinate temperature and for a determinate time.
  • the manufacturing process continues by cutting the natural stone plates of a module into two through a middle plane, thus obtaining two compound tiles, after which the visible face of each tile is shaved and polished.
  • FIG. 1 shows a lower sheet of fibre cement with a section in which the strip retaining the adhesive may be observed.
  • FIG. 2 shows a lower sheet of fibre cement with channels for retaining adhesive.
  • FIG. 3 shows a stack of modules, fibre cement-marble-fibre cement, in which one may observe a detail of the lower sheet of fibre cement with retention channels.
  • FIG. 4 shows a detail of a finished compound tile.
  • FIG. 5 shows a detail of the glue contact points for placing the sheets of fibre cement upon and under the marble, thus preventing their relative movement.
  • FIGS. 6 and 7 show two consecutive operations of the cutting process of a module of fibre cement-marble-fibre cement into two tiles with a visible marble face.
  • the compound tile is made up of a natural stone plate 3 , preferably marble, and a supporting sheet 1 , 2 , a fibre cement compound whose composition is as follows:
  • silica between 40 and 50% by weight with respect to the total composition
  • sand between 4 and 6% in weight with respect to the total composition, with a grain size of 0.1 mm.
  • cellulose fibre less than 6% by weight and preferably between 4 and 5% by weight with respect to the total composition.
  • size stabilising agents between 2 and 8% by weight with respect to the total composition, said agents being preferably alumina, kaolin and mixtures thereof.
  • water-repellents between 1 and 3% by weight with respect to the total composition, belonging to the siliconate group, preferably potassium methyl siliconate at a 15% concentration dissolved in water and applied to the surface with a ratio of 0.3 and 0.4 l/m 2 .
  • size stability of the fibre cement sheet 1 , 2 can be increased as the movement of humidification is reduced from 0.45% to 0.30% after an accelerated ageing process.
  • Another component which may be added to the mixture is a pigment of synthetic iron oxide which is useful in that it enables one tile to be distinguished from another, for example when a different pigment is used for each colour of the marble 3 or for protection against the elements.
  • the compound tile For adhesion between the two materials, the marble plate 3 and the fibre cement sheet 1 , 2 , the compound tile uses an adhesive, preferably epoxy resin with two components 8 which has micro-granules or micro-nodules in its composition with a mean diameter of 0.1 mm.
  • the purpose of said micro-granules is to ensure a space between the marble plate 3 and the supporting sheet in order to ensure a minimum adhesive layer, as this is necessary due to the processes explained below.
  • the manufacturing process of the compound tiles with marble visible face 3 is carried out in the following stages:
  • plates are cut with a thickness of more than twice that of the final thickness of the marble plate 3 of the tile to be obtained;
  • each module is made up of a supporting lower sheet 2 with a larger surface size than the following ones, the marble plate 3 on the lower sheet 2 and a supporting upper sheet 1 on the marble plate 3 , forming modules of fibre cement-marble-fibre cement.
  • the lower fibre cement sheet 2 of each module having a greater surface area than the others, has means 4 , 6 to retain the resin 8 in each module, preventing said resin from making contact with the other modules.
  • Said retention means consist of peripheral channels 4 with a depth of 1 to 1.2 mm or a peripheral strip 6 with a height of 3 mm, preferably made of wax.
  • the stacks of modules are introduced into an oven with controlled humidity for curing the adhesive at a temperature ranging between 50 and 60° C. for approximately 1 to 2 hours.
  • the final product of this process is a square or rectangular tile whose usual formats are:
  • the thicknesses based on the resulting plates of natural stone with a thickness of 7 mm, will be the result of adding the applied fibre cement sheet, according to the following variants:
  • the natural stone plate After the processes of smoothing, calibration and polishing of the resulting tiles, the natural stone plate has a thickness of 6 mm, with a perfectly polished surface and a slight bevel on its four edges. The rest of the thickness corresponds to the adhesive and the supporting fibre cement sheet.
